A Simplified Approach for Sinus Augmentation to Avoid Sinus Membrane Perforation: An Analysis of 400 Cases

Area of Science:

• Dentistry
• Oral Surgery
• Implantology

Background:

• Crestal sinus augmentation is crucial for dental implant placement in posterior maxilla with bone resorption.
• Traditional techniques carry risks of sinus membrane perforation and are technique-sensitive.
• New instrumentation and techniques aim to simplify the procedure and reduce complications.

Purpose of the Study:

• To evaluate a novel surgical concept and instruments for crestal sinus elevation.
• To determine the incidence of sinus membrane perforation using the new technique.
• To assess the efficacy of the new approach in cases of maxillary atrophy.

Main Methods:

• Utilized two kits (Kit A for <4mm and Kit B for >4mm sub-sinus bone height).
• Employed a minimally invasive, precise surgical protocol for crestal sinus elevation.
• Analyzed 400 cases (100 with Kit A, 300 with Kit B).

Main Results:

• Achieved a 97% success rate in avoiding sinus membrane perforation across all cases.
• Demonstrated the effectiveness of the new kits in managing varying degrees of maxillary atrophy.
• The technique proved successful in facilitating sinus bone grafting.

Conclusions:

• Transcrestal sinus elevation with the All Secure Sinus Elevation Kit (ASSEK) offers a safe alternative to older methods.
• The kit's design minimizes complications, particularly sinus membrane perforation.
• This simplified, minimally invasive surgery improves outcomes for sinus augmentation and dental implant placement.
